<h3 id="环境配置"><a href="#环境配置" class="headerlink" title="环境配置"></a>环境配置</h3><pre><code>首先我们要进行相对应的环境配置，除了相对应的SpringBoot启动器和Web启动器外，还添加了SpringBoot默认模板引擎Thymeleaf的相应配置，因为我用的是SpringBoot1.5.19的版本而不是2.0所以thymeleaf默认的是2.0版本，thymeleaf-layout默认是1.0，我们需要将thymeleaf版本改成3.0和其thymeleaf相对应的2.0版本，如图所示</code></pre><p><img src="http://wx3.sinaimg.cn/mw690/007dV4f5ly1g0xwdzpulsj30om0ewabf.jpg" alt="img"></p>
<p>​    重点是Shiro，使用版本是1.4.0</p>
<p><img src="http://wx4.sinaimg.cn/mw690/007dV4f5ly1g0xwsx3g29j30od03swej.jpg" alt="img"></p>
<h3 id="Shiro配置"><a href="#Shiro配置" class="headerlink" title="Shiro配置"></a>Shiro配置</h3><p>​    shiro配置主要包含三步:</p>
<p>​    1.创建ShiroFilterFacoryBean</p>
<p>​    2.创建DefaultWebSecurityManager</p>
<p>​    3.创建自定义的Realm类，Shiro会从Realm类中进行认证逻辑和授权逻辑的处理</p>
<p><img src="http://wx2.sinaimg.cn/mw690/007dV4f5ly1g0xx7zccdqj30oh0fcmyk.jpg" alt="img"></p>
<p><img src="http://wx3.sinaimg.cn/mw690/007dV4f5ly1g0xx7zpwb5j30px0av0th.jpg" alt="img"></p>
<h3 id="登陆认证"><a href="#登陆认证" class="headerlink" title="登陆认证"></a>登陆认证</h3><p>​    shiro登陆认证也是分为三步：</p>
<p>​    1.通过SecurityUtils获取subject对象</p>
<p>​    2.封装当前登陆用户的账号密码</p>
<p>​    3.执行登陆方法通过抛出shiro封装好的异常来确定登陆状态</p>
<p><img src="http://wx3.sinaimg.cn/mw690/007dV4f5ly1g11i5065t8j30mm0fr75c.jpg" alt="img"></p>
<h3 id="执行登陆认证"><a href="#执行登陆认证" class="headerlink" title="执行登陆认证"></a>执行登陆认证</h3><p>​    通过认证出来的token对象取出登陆用户的信息，并判断该用户的状态,如果不存在则直接返回空，</p>
<p>shiro抛出用户名不存在的异常，然后直接返回一个AuthenticationInfo的实现类，我们这里直接返回一个SimpleAuthenticationInfo就行了，将从数据库取出来封装了所有相关属性的user和密码返回就行，shirp会帮我们进行密码校验。</p>
<p><img src="http://wx1.sinaimg.cn/mw690/007dV4f5ly1g11i99uw9kj30rg0a93z6.jpg" alt="img"></p>
<h3 id="执行授权逻辑"><a href="#执行授权逻辑" class="headerlink" title="执行授权逻辑"></a>执行授权逻辑</h3><p>​    创建一个SimpleAuthorziationInfo对象，将当前用户的角色以及对应的权限通过addRoles或者addStringPermissions方法加入Info。因为用户角色权限的关系需要根据实际情况来选择，图中给了点示例，可以参考，最后将info对象返回。</p>
<p><img src="http://wx3.sinaimg.cn/mw690/007dV4f5ly1g11io4agslj30p90dhmy2.jpg4f5ly1g11ijqrkbzj30qj0ekdgt.jpg" alt="img"></p>
<h3 id="shiro标签"><a href="#shiro标签" class="headerlink" title="shiro标签"></a>shiro标签</h3><p>​    以上已经完成了简单的权限控制，想在界面更好的优化（比如隐藏相应的资源）可以通过shiro的标签来进行操作，需要导入额外的依赖thymeleaf-extras-shiro，html头文件也需要做相应的声明，以下举例两个简单的shiro标签</p>
<p><img src="http://wx1.sinaimg.cn/mw690/007dV4f5ly1g11j0lh9vhj30ph04jdg1.jpg" alt="img"></p>

<h3 id="写在末尾的话"><a href="#写在末尾的话" class="headerlink" title="写在末尾的话"></a>写在末尾的话</h3><p>​    第一次写博客第一次用shiro，不论是技术还是博客都很粗糙，我依然很菜，希望大家学习顺利，成为大牛。</p>
